Situation and medium-term forecast

Alder pollen may still burden!The peak burden period was alleviated, but moderate alder pollen concentrations are currently still measured. Therefore, a continued moderate burden has to be expected.The flower of hazel has progressed further and will cause only low pollen concentrations on a widespread level. Only in some regions a moderate burden is possible (West and South of Austria).The flowering potential of hazel is nearly completely exploited and that of alder mostly. This means that the main burden from the flower of hazel and alder is overcome! A longer lasting pollination has to be expected only for mid-altitude regions under favorable conditions. This year´s hazel and alder pollen season proceeded above-average concerning their intensity.

Note: Pollen allergy sufferers may react differently to the current situation. While some will profit and feel a relief/hardly a burden after the decrease of the peak, others will suffer significantly from the prevailing pollen concentrations.

The flower of ash is not yet imminent, but is expected for end of March, if weather conditions are favourable. We expect a less intense flower of ash for this year.The forecast data of the readiness to flower for birch indicates a potential start of flowering towards the end of March/beginning of April. We expect an above-average flower of birches for 2018.

What else: The pollen spectrum contains pollen from cypresses and yews, poplar and elm in addition, which is of a low allergological importance.

Note: The model results give an indication of the expected start of flowering, based on information provided by local pollen warning services with direct reference to the local situation. Start of flowering is not to be equated with the beginning of the pollen season. When the start of flowering is achieved, the majority of the plants have the potential to release pollen, but only when weather conditions are favourable.
